    Designed for the harshest work environments, EXTRAGUARD upper technology offers robust protection, even after months of use or constant wear in challenging wet conditions.

    When dry, the robust and abrasion-resistant upper material construction is 40 percent lighter than leather.

    Due to the low water absorption construction, the upper remains lightweight in wet conditions.

    The upper hardly absorbs any moisture from the outside even after extensive use or loss of the water repellent finish.

    Significantly faster drying time compared with conventional uppers used for safety footwear.

    The EXTRAGUARD upper is easy to clean and does not require specific care products as needed for conventional footwear.

    External moisture cannot penetrate beyond the low water absorption construction layer. The result: reduced conductive heat loss, consequently feet stay dry and comfortable.

    NEW UPPER TECHNOLOGY: EXTREME ROBUSTNESS COMBINED WITH LASTING LIGHTWEIGHT

    Robust, waterproof, and breathable safety footwear must offer reliable and durable protection in all working situations and weather conditions. While wearers were looking for increased lightweight and comfort in their safety footwear, they were often facing the dilemma that robust protection came with the downside of more weight or less comfort.

    Now for the first time, the new three layer EXTRAGUARD upper technology is paving the way for the construction of a new generation of highly robust and durably lightweight safety footwear.

    When dry, the EXTRAGUARD upper material is already up to 40 percent lighter than leather, and due to its low water absorption properties, the footwear keeps its lightweight properties even after extensive use in extremely wet and muddy conditions.

    Stays lightweight when wet

    Compared with conventional safety footwear GORE-TEX EXTRAGUARD footwear engineered with EXTRAGUARD upper technology has very low water absorption, gaining almost no weight when wet- confirmed by the water bucket test.

    Gore static water bucket test: Boots are submerged at 10 cm water level.

    The image shows a infrared image demonstrating that the heat loss of a wet leather boot is significantly higher  than that of a wet GORE-TEX EXTRAGUARD boot.

    Reduced heat loss when wet

    The conductive heat loss from a GORE-TEX professional shoe with EXTRAGUARD upper technology (shoe on the right) is considerably less than any identical leather version. The feet stay dry and comfortable.

    EXTRAGUARD UPPER MATERIAL AND SUSTAINABILITY

    W. L. Gore & Associates is committed to continuously improving the environmental impact of its products without compromising on durable performance. All new product technology developments need to support the Sustainability Strategy.

    The EXTRAGUARD upper is a clear example of us reducing our environmental impact: fewer chemicals used than in the production of conventional upper materials, less water consumption, and reduced CO2 emissions equate to a smaller carbon footprint when compared with safety footwear made of conventional, highly robust upper materials.

    The innovative and vegan upper material is chromium-free, supplied with consistent quality (it is well-rolled), and no longer requires extra inspection on receipt, significantly reducing work and material waste.
